by Sergio, 3 years agoEsta extensión hace una gran labor en proteger la privacidad del usuario.
Hace que puedas tener el control sobre como actúa el JavaScript en las paginas que visitas y permite protegerte de muchas técnicas sofisticadas elaboradas para rastrear tu actividad y los datos sensibles de tu ordenador (el tipo de pantalla que usas, la tarjeta gráfica, el sistema operativo, etc.)
No solo brinda privacidad. También hace que la navegación web sea más segura ya que ayuda a mitigar posibles vulnerabilidades de los scripts.
¡Recomendadísima junto a uBlock Origin!

- Rated 2 out of 5by What???, 3 months agoExtremely complex but the only working fingerprint spoofing extension out there now that the original Fingerprint Spoofing extension/add-on has been removed from Github because later reiterations are malware and developer has stopped supporting it more than 5 years ago. On Firefox, but not Chrome it ramps up CPU usage and RAM.

posted 2 months agoThe CPU and RAM usage should be signifficantly lower startng from 0.19.1 that is just released. Please let us know if you observe issues in 0.19.1. We prefer the issue tracker or email jshelter@gnu.org. - Rated 3 out of 5by RYX, 4 months agoThe fingerprint protection this offers is comprehensive and is the only one that I have encountered that protects against the "Creepjs" fingerprinter.
I have tested it against multiple other sites like browserleaks and fingerprint/demo.
HOWEVER, about half the internet does not work with this extension because CloudFlare blocks you with a message "This Browser Is Out of Date" which makes you turn off the extension. If you can fix that issue, I'll mark this to 5 stars.Developer response
posted 2 months agoCan you try the following?
* Click on JShelter badge icon -> click "Global settings" in the popup.
* You should see the option page
* Locate "Fingerprint Detector" section neear the bottom of the page.
* Click "Manage exception list ⤵" (it should be the lowest button on the page).
* Add "challenges.cloudflare.com" to the list.
* Click "JS Shield details" in the menu
* On the top, add "challenges.cloudflare.com" and select "Turn JavaScript Shield off" (or test other level if you see fit).
Try to visit the affected page and report back if you were successful (for example to jshelter@gnu.org). I think that this is a good candidate for a FAQ entry. - Rated 4 out of 5by BaraShiro, 6 months ago(Updated 24-09-24) Very powerful but complex tool. Defeats fingerprinting, but requires some tinkering in order to not break almost every page on the internet. The memory issues seems to be fixed in version 0.19.1.

I used about:memory to discover that this was the culprit. After I disabled JShelter, the CPU usage and RAM dropped.

I recommend it to anyone that will listen. On rare occasions some sites will break because they're using a really aggressive captcha or spam detection platform. Lowering the settings on JShelter and refreshing fixes this. I also disagree that notifications should be shown by default, if at all. Every site is using fingerprinting of some sort nowadays, so you just get a notification every time you go to a site and the notifications become noise.

- Rated 3 out of 5by Viking Helmet, 2 years agoAs much as I appreciate the concept behind this and would like to give it a higher rating, it breaks too many websites and virtually anything that uses CAPTCHA. I'll continue to keep it around, but some sites will flat-out ignore your request and others will fail to verify your humanity while it's enabled.
